Also, I can say for a fact that simply re-installing the drivers will not reset the system back to where mine started with the fresh install.

While I was trying to fix my problem last weekend, I tried uninstalling/re-installing the drivers but it would end up right back to the same garbled out of sync image on my TV. No scrolling 640x480 display. It had retained whatever f'ed up screen settings.

The only way around this is to find all of the settings locations.

Also, does anyone know how Ubuntu stores the current screen resolution? (from going to the built in menu to change resolutions) I also see resolutions show up in that menu that are not in my xorg.conf file including the 1152x648 res that I'm using.

4. Use the ATI control panel to enable the dongle at which point you should have a clone display. At this point I had a scrolling 640x480 desktop on my TV.

I have an ATI X1800 which uses a Svideo/Component connection rather than a Dongle for the card to Component interface. Where on the ATI Control Panel did you see an option to enable the dongle? I did try a cloned desktop but nothing ever displayed on my HDTV it remained blank, including after a reboot. My Xorg.0.log always showed the startup of X disabling "CV" connection because it could not find EDID information. I tried this with the ATI drivers prior to 7.11, I have not tried the latest drivers yet.

Thanks for your reply.

I have a X850Pro which I think has the same combo component/S-video output as yours. We I say enabled, I just mean that I enabled the display in the control panel (my TV shows up as one of the usable displays). I don't know if it makes a difference, but I am running the 7.11 drivers.

Talon95:
I have upgraded my graphics drivers to 7.11 and still no joy with component video output or Catalyst Control Centre selection of HDTV formats (none are displayed or selectable). I have Compiz-Fusion working and all the other accelerated features of the latest driver.

Under the Catalyst Control Centre I do have Clone mode on and have forced CV on all to no effect.
From /etc/ati/amdpcsdb file:
…
[AMDPCSROOT/SYSTEM/DDX]
FSAAEnable=Soff
FSAAScale=S2
VideoOverlay=Son
OpenGLOverlay=Soff
DesktopSetup=Sclone
EnableMonitor=Scrt2,cv
IgnoreEDID=Strue
ForceMonitors=Scrt1,cv
TVFormat=SNTSC-M
TVStandard=SVIDEO
TVOverscan=Soff
TVHPosAdj=S0
TVVPosAdj=S0

Considering you have a working Component Video configuration please send me your Xorg.0.log, amdpcsdb files. If you feel extra kind also your /etc/X11/xorg.conf file. At least I would see what a working configuration looks like.

Talon95,
Sorry I did not get back to you sooner but I was sick since for a week and had not touched the computer.

The information you sent me was very interesting. I can see clearly where my CV connection gets disabled and yours does not.

I upgraded my graphics drivers to 7.11 then cobbled together parts of your amdpcsdb and your xorg.conf. When I tried this new configuration it did not help but I felt closer to a solution. I had ended up with the TV as the primary display under the Control Center but still no HDTV formats to select.

I have just upgraded to the 7.12 drivers but that seems to have broken Compiz-Fusion and I have not tried anything else while I was sick.

I have always started Ubuntu with both the HDTV and CRT attached and powered on.
